2 Claims.

This invention relates to containersandpar'- ticularly to containershaving removable heads and means for holding the heads .normally .inplace, an object being to provide a construction wherein the head willbe maintained in airtight condition notwithstanding varying changes intemperature and atmospheric conditions.

Another object of the invention is to provide a container which may bemade from laminated ber and provided with afiber, wooden or metal headassociated with an expansible rim adapted to expand and contract as thehead and container expand and contract with changes in temperature orhumidity in order to maintain the head airtight at all times.

A further object of the invention is to provide a container with aclosure structure including a head and a metal rim provided with anexpanding section arranged to maintain the head airtight notwithstandingvariations in temperature and humidity, and expansion and contraction ofthe head, body portion and/or rim.

In the accompanying drawingv v Fig. 1 is a side view of a containerembodying my invention, a portion being broken away to illustrate theclosure construction;

Fig. 2 is an enlarged fragmentary sectional view through Fig. 1approximately on the line 2 2;

Fig. 3 is a top plan view on a reduced scale of the rim shown in Fig. 1;

Fig. 4 is a view similar to Fig. 3 but showing a slightly modiiiedconstruction of the invention; and

Fig. 5 is an enlarged perspective view illustrating one of the resilientmetal sections.

Referring to the accompanying drawing by numerals, I indicates the bodyof the container which may be provided with any kind of bottom but whichis provided with a special closure at the top. This container may bemade of any de-4 sired material but is preferably made from laminatedfiber. The container has an opening adjacent one end which is providedwith a removable head 6 releasably held in place by means of clampingring 4. Adjacent the open end, the container is provided with anexternal annular groove 2 for receiving the turned-in annular edge 3 ofthe metal rim 4. The rim is also provided with an overlapping ange 5which overlaps the the head 6, which head may be made of wood, ber, orother material. Wood is used quite generally in heads for fibercontainers and when the head 6 is formed of wood it may be provided witha flange 'I resting on the top edge of the container, or this ange maybe eliminated andthe head allowed to rest solely on the shoulders. Inthis form of head and preferablyin al1 formshof head, there is provideda moisture-proof or mois- -.5. ture-resisting thin lining 9 whichextends over the inner surface of the head 6 along the peripheral partand over the top of the wall ofthe container as illustrated at the leftin Fig. l.

Various forms of' metal bands have been pro- 1() vided heretofore forholding the head 6 in place and also means have been provided fortightening the bands so that when the head is first applied -it will beair and liquid tight. However, it has been found that while the head maybe perl5 fectly tight when rst applied, it oftentimes loosens up andallows air, moisture and other foreign matter to enter or leave,particularly as a result of changes in temperature or atmosphericconditions. This action is sometimes known as breathing, and is highlyundesirable wheneverit is necessary to protect the contents ofthecontainer from contamination by foreign'matter or from exposure to airor moisture.

By means of my present invention, I provide a ggfpermanently tight headwherein breathing is eliminated even though the container is subjectedto changes in temperautre and atmospheric conditions. In order to securethis desirable result, the metal rim 4 has been made circumferentially3'6"?, resilient or elastic to a limited extent as, for instance, by theuse of an elastic section IIJ formed of transversely corrugated springsteel, though other elastic means may be usedl without depart.-

ing from the spirit of the invention. The rim 4 3%?1 is a split rim andis made from suitable strong material such as steel or other metal, .andthe section I0 is made from a strong resilient metal, as

for instance, tempered steel. Section Ill may be secured vto one end ofrim 4 by welding or. other mmeans, as for instance, rivets `I I and I2,as shown in Fig. l, and a pivotal rivet I3 connects theother end ofsection I0 to the closing and locking lever I4 intermediate its length.A second pivotal rivet I5 extends through lever I4 adjacent the endthereof and connects it to the opposite end of rim 4, as shown in Figs.1 and 2.

Rim 4 is preferably formed so that'the ends thereof overlap, as shown inFig. 2. It will be observed that section I0 is connected to `andprojects beyond one end of the rim 4 and that lever I4 is connected tothe rim adjacent the opposite end. It will also be noted that there isprovided a pressed-up loop I6 in the rim adjacent pivotal connection I5into which the end I'I of lever I4 extends. The end I'I is provided witha notch I8 so that when the parts are in position, as shown in Fig. 1,part of the loop may be bent inwardly into notch I8 and thereby preventaccidental opening of the lever.

To place rim 4 around the upper end of the container to hold head E inposition, lever I4 is iirst pivoted upwardly in a clockwise direction,as viewed in Fig. 1V, so as to expand the rim. The rim is then ttedaround the container with the annular ledge 3 fitted into the externalgroove 2 and 'with the ange 5 overlapping the flange 1 of the head 6.The lever is then pivoted in a counter-clockwise direction so as tocontract the rim and the end I'l is inserted into loop I6, in the mannershown. The lever can be retained in position against accidentaldisplacement by bending the loop inwardly into notch I8. In thisconnection, the pivotal pointsl and I3, for connecting the lever to theend of the rim and to the resilient section I U, are preferablysoarranged that when the lever is in locked position, as shown in Fig.1, the pivotal points are out of alignment with each other, the pivotalpoint I5 being disposed slightly above the pivotal point I3 so that thenatural tendency of the rim to expand circumferentially, due tothetension when it is locked, serves to exercise a locking, rather than areleasing action on the lever.

The parts are so proportioned that when they are moved to the positionshown in Fig. 1, the section I0 is sprung or separated somewhat thoughnot Vto its fullest extent. By reason of this fact, the rim may expandor contract as may be required. When the parts are arranged as shown inFig. 1, if the containeris subjected Ato variations in temperature orhumidity, the section I0 will expand or contract as the case may be, andmaintain the tight connection of head 6 with the container. In this waythe contents of the container are protectedfrom exposure to air orAmoisture and Afrom contamination by foreign matter.

The construction shown in Figs. 1 to 3, inclusive, provides a rim 4which is in one piece, `and the corrugated spring section I0 is securedto one and thereof. However, the rim may be formed inV any desirednumber of pieces, and one or more sections similar tovsection I0 may beconnected at-any desired circumferential position in the rim. Thus, inFigs. 4 and 5, a slightly modied construction is disclosed wherein therim 4' is vthe same as rim 4 except that it is divided at I9 and-provided with a resilient section I0. This form of the invention hasthe resilient section I0, lever I4 and associated parts as shown in Fig.l, and lin addition the section ID which is substantially diametricallyopposite section I0.

The construction of the section I0 is the sameas section I0 except thatit is riveted or rigidly secured at both ends, as illustratedparticularly in Fig. 5.V In this iig-ure, it will .be seen that a pairof rivets 20 connect one end to one part of the rim 4' and rivets 2|connect the other end to the other part of the rim 4.

The resilient sections I0 and I0 are preferably formed with outwardlyextending corrugations 22 and ilat connecting sections 23 so as toprovide the desired resiliency and also the desired resistance. Threebowed-out sections 22 have been shown in the drawing but it is evidentthat a smaller or greater number may be used without departing from thespirit of the invention.

While the above outlined form of clamping rim for holding the head 6 inplace is particularly desirable for use with iiber containers, it may beused with containers made oi' other material without departing from thespirit of the invention.

It shouldbe understood, of course, that modications may be made in theillustrated embodiment of my invention without departing from theinvention as set forth in the claims.
